So small update. Had the front tyres replaced by SMG this morning, they shipped up from KZN and popped into JSN to get it sorted. Great service from JSN I must say. The front left tyre had a pothole bubble and was affecting the handling quite badly. Since the tyre has been replaced, on the brief trip to the office, felt like a different car. So very happy with the outcome.
Overall, I am really loving the car, it is a completely different driving experience from the 550. Although the dimensions are ultimately not that different, it feels smaller (active integral steering maybe?), it feels like it wraps around you with the ergonomics and the lower roofline, and the way the centre console cascades down through the centre of the car. The details are amazing. If anyone has experienced the interior, the door pulls on the front doors are works of art. The seats are incredibly comfortable. And the exhaust note is far more aggressive (even in Comfort) than the 550 was.
So very happy!
